Industrial Medical Military Aerospace KEMET Surface Mount Capacitors 1.0000100-1.0000700 Steel 100.0000000 012 20 40 µ Value 60 80 100 Magnetic Permeability is the degree of magnetization a material obtains in response to an applied magnetic field. The more conductive a material is to a magnetic field, the higher the permeability. As comparison, the magnetic permeability of air is essentially 1 with a µ value of 1.0000037 with steel having a µ value near 100.
